After the installation is complete, insert the SD card, power on the device and check that
the \B2Q welcome screen and/or demo appear.
+ \b {Setup for Nitrogen6_Lite Device}
+ The boot script requires the environment variables, \c dtbname and \c gpumem, to identify
+ the device as Nitrogen6_Lite. Otherwise, the device is booted with the default GPU
+ memory setting of 512MiB, which is more than what is available on the Nitrogen_Lite devices
+ (128MibB).
+ Use one of the two following options to enable the scripts boot the device
+ with correct GPU memory setting:
+ \list
+ \li Write a \c uEnv.txt file on to the boot partition of SD card with the following
+ content:
+ \badcode
+ gpumem=67108864
+ dtbname=imx6dl-nit6xlite.dtb
+ \endcode
+ \li Access the device's console and run the following commands on the U-Boot prompt:
+ \badcode
+ U-Boot > setenv gpumem 67108864
+ U-Boot > setenv dtbname imx6dl-nit6xlite.dtb
+ U-Boot > saveenv
+ \endcode
+ \endlist
